An edge device includes a first antenna array that includes a first portion and one or more second portions. The edge device includes control circuitry that senses a surrounding area of the edge device by use of the first portion of the first antenna array.

An apparatus obtains a set of radio data comprising signal strength related values for radio signals transmitted by a transmitter with an association of each signal strength related value with a representation of a geographical location. The apparatus applies a frequency transform to the obtained set of radio data to obtain transform coefficients, each transform coefficient comprising a transform index and an associated transform value. The apparatus selects a subset of transform indices having more significant transform values than the remaining transform indices and compresses the transform indices by encoding each transform index exploiting a probability of occurrence of an index value of a respective transform index. The same or another apparatus decodes the compressed transform indices again for use in position operations.

A first display device and method are provided for accelerating the coarse relocalization process of the first display device by generating a session-specific identifier and sending it to a second display device, which transmits the identifier to a cloud service, which returns at least a portion of a map data set corresponding to the identifier. The returned map data set is then stitched into the local map data of the first display device to create an integrated map, which is used to render one or a plurality of holograms. The first display device may comprise a processor, a memory operatively coupled to the processor, and a fingerprint program stored in the memory and executed by the processor.
